Now to the dangerous brawl that broke out high on mt. Everest. Three professional climbers getting into a terrible fight with dozens of sherpas. To people who are hired to guide them to the summit and neal karlinsky has their story. Reporter: It sounds almost too outrageous to be true. Three of the world's most elite climbers fighting for their lives atop the world's tallest mountain. Not against the elements but what's described as an angry mob of nearly 100 sherpas, the himalayan mountaineers who aid climbing teams. They promised us they're going to kill us. It's a bad movie. Reporter: Ueli steck described the scene as he, italian simone moro and jonathan griffith just barely escaped. They threw a really, really big rock into the tent. If I got hit by the rock I would be dead immediately. Reporter: They credit melissa arnot with calming the sherpas and saving them. She spoke with us from the mountain overnight. I felt that it was much less likely that they would hit me actually or hit me with a rock or anything else just being a woman. Reporter: The bizarre battle began at what's known as camp 3. The sherpas were attaching ropes and say the trio ignored a request to wait and instead climbed around them possibly knocking ice on to one of them. Then as the three climbed down to camp 2 they say nearly 100 sherpas were waiting to attack them. It would certainly be terrifying but the one thing we haven't heard from any of the sherpas that were there and until we do we should probably withhold judgment. Reporter: This morning the three have abandoned their climb and left the mountain but not before signing in makeshift agreement drawn up by climbers on both sides to never again resort to violence on a mountain that's proven all too deadly even when everyone is working together.
